A Tel Aviv University researcher has found that young men who smoke are likely to have lower IQs than their non-smoking peers. His study, which was conducted on young men in the Israeli army, found that the average IQ for a non-smoker was about seven points higher than that of a smoker. Young men who smoked at least a pack a day has an even lower average IQ. "People with lower IQs are not only prone to addictions such as smoking," said Prof. Mark Weiser of Tel Aviv University's Department of Psychiatry. "These same people are more likely to have obesity, nutrition and narcotics issues."
